Local fix
Problem summary
**************************************************************** * USERS AFFECTED: ALL DB2 for z/OS V10 users * **************************************************************** * PROBLEM DESCRIPTION: The DB2 directory data base (DSNDB01) * * could experience significant space * * growth resulting from BIND/REBIND * * operations, DDL or Utility activity. * **************************************************************** * RECOMMENDATION: * **************************************************************** SPT01 table space. The deleted space within the same UR that is performing a REBIND operation can not be reused until the UR is committed. In addition, the subsequent insert of the new package may not reuse the committed delete space promptly due to the clustering order of the record within the table space. As a result, the SPT01 table space could experience significant space growth resulting from a large volume of concurrent BIND/REBIND operations.
Problem conclusion
DB2 has been modified to allow a UR to reuse its own deleted space within the same commit scope if it has exclusive control of the page. In additional, the search algorithm has also been changed to reuse the deleted space sooner. In any case if the UR doing BIND/REBIND process needs to roll back, the log apply phase will process the log record by redoing the change physically instead of pseudo delete process. These changes only apply to the UTS table space created in the DB2 directory data base (DSNDB01).
